“…It was found that buckle pressures of 454 g (the minimal criterion for rigidity used by many sleep laboratories) were achieved in 27/35 (77%) patients. 8 Bosshardt and co-workers showed that a nocturnal penile tumescence rigidity of 80% (70% being sufficient for intercourse) 40 was the norm after 6 months in their group of 26 patients. They also showed that induced ischemia could result after 30 min of applying the constriction rings.…”

“…7 Despite this, the device faced strong skepticism among the medical community and patients. Instrumental in overcoming these skepticisms and popularizing the device were the early works of Nadig 8 and Witherington 9 in establishing its efficacy and safety profiles. It was thought to have finally gained acceptance by the medical community with Lue's commentary in the Journal of Urology: 'I recommend a vacuum constriction device to all of my patients (except those with coagulation disorders and sickle cell disease) as the initial medical option'.…”

Vacuum therapy (VT) utilizes negative pressure to distend the corporal sinusoids and to increase the blood inflow to the penis. Depending on its purpose, VT could be used as vacuum constriction device (VCD), with the aid of an external constricting ring which is placed at the base of penis to prevent blood outflow, maintaining the erection for sexual intercourse. Also, as a vacuum erectile device (VED), without the application of a constriction ring, just increases blood oxygenation to the corpora cavernosa and for other purposes. The emerging of phosphodiesterase 5 inhibitors (PDE 5 I) for the treatment of erectile dysfunction (ED) eclipsed VCD as therapeutic choice for ED; however, widespread usage of VED as part of penile rehabilitation after radical prostatectomy and other purposes rekindle the interest for VT. The underlying hypothesis is that the artificial induction of erections shortly after surgery facilitates tissue oxygenation, reducing cavernosal fibrosis in the absence of nocturnal erections, and potentially increases the likelihood of preserving erectile function. Due to its ability to draw blood into the penis regardless of nerve disturbance, VED has become the centerpiece of penile rehabilitation protocols. Herein, we reviewed the history, mechanism, application, side effects and future direction of VT in ED.

“…given FDA approval in 1982, the technology was eventually adopted into the medical community with the aid of two urologists, Drs Perry Nadig and Roy Witherington, who conducted the first studies regarding its efficacy, [45][46][47][48] and the first device received Federal Food and Drug Administration (FDA) approval in 1982. 48 The components of the device are generally threefold.…”

Even nerve-sparing radical prostatectomy damages the cavernous nerves and leads to temporary erectile dysfunction (ED) in men recovering from prostate cancer surgery. Historically, patients recovering from prostate cancer surgery have been advised that the return of erectile function (EF) can take from 6 to 18 months, or even longer. Unfortunately, the return of sexual function in these patients remains variable, but is generally thought to be dependent on the individual patient's pre-surgery EF, as well as the degree of cavernous nerve disruption during prostate removal. Recently, there has been a growing movement to proactively treat patients postoperatively for presumed nerve damage to stimulate nerve recovery and possibly reduce the degree of irreversible damage. This would reduce the on-demand therapy these patients would require, and hopefully remove the requirement for an implantable prosthesis. The underlying hypothesis is that the artificial induction of erections shortly after surgery facilitates tissue oxygenation, reducing cavernosal fibrosis in the absence of nocturnal erections, potentially increasing the likelihood of preserving EF. Vacuum erection devices (VED), because of their ability to draw blood into the penis regardless of nerve disturbance, have become the centerpiece of penile rehabilitation protocols. This review will discuss the pathophysiology of radical prostatectomy induced ED and the rationale for rehabilitation. It will then discuss current protocols, including those involving the VED.
